Epoxy flooring for commercial spaces starts with the slab, not the topcoat. We assess the concrete, test for moisture, grind to the system profile, apply primer and body coat with the right aggregate for slip resistance, then seal with a topcoat matched to the chemical and traffic load. Oshawa Concrete installs complete epoxy systems for warehouses, service bays and manufacturing plants, with a free written estimate before work begins.
Epoxy coatings fail when the concrete underneath is not ready. Moisture, contaminants, uneven surfaces and old failed coatings all cause new epoxy to lift, blister or peel within months. The slab is the substrate; the epoxy is only as good as what it bonds to.
Our process begins with a moisture test and visual assessment of the existing slab. We diamond-grind to the manufacturer's specified profile, removing laitance, old coatings and surface contaminants. Where moisture vapor is high, we apply a moisture-mitigation primer before the body coat. Cracks and joints are filled with a compatible filler. Only then does the primer, body coat and topcoat go down in the right sequence with proper cure time between each layer.
We inspect the existing concrete, measure moisture vapor, identify cracks or uneven areas, and determine what prep work is needed before coating can begin.
Grind and prepare the surface
Diamond grinding removes old coatings, contaminants and surface laitance to the manufacturer's prep profile. Cracks are filled and the slab is left clean and profiled for primer adhesion.
Apply primer and body coat
The primer bonds the epoxy to the concrete. The body coat is applied at the specified thickness. Slip-resistance aggregate is broadcast into the wet body coat where needed for safety.
Topcoat and return to service
The topcoat seals the system and provides the wear surface. The floor cures to the manufacturer's schedule, then is returned to service at the timeline we provide before the install.

Choosing the Right Epoxy Specification Prevents Failure
Commercial epoxy systems are not interchangeable. A warehouse floor, a service garage, a food-processing plant and a retail showroom each need a different system spec based on chemical exposure, traffic type, temperature swings and slip requirements. Installing the wrong system in the wrong environment will fail in months regardless of how well the install was executed.
We specify based on the actual use case. A service bay gets a system rated for hot tires and automotive fluids. A wash-down area gets chemical resistance and slip aggregate. A food-processing floor gets a system rated to that environment. When the install is part of a larger renovation, we coordinate with adjacent polished concrete in office zones and loading dock work so all floor systems transition cleanly.
Slab prep, chemical resistance, slip ratings and system selection for commercial epoxy.
A properly specified and installed system lasts the better part of a decade or longer in most commercial environments. Wear comes from traffic and chemicals; the system spec determines how it handles each. We size the spec to your use.
Diamond grinding to the manufacturer's prep profile is our standard, removing contaminants, old coatings and surface laitance. Where moisture testing flags a high-vapor slab, a moisture-mitigation primer goes on first. Skipping prep is why coatings fail.
Yes, with the right system spec. Wash-down floors get a system with chemical resistance and slip aggregate; food processing gets a system rated to that environment; service garages get a system rated for hot tires and automotive fluids. The system matches the use.
Foot traffic typically a day after the topcoat; full vehicle or chemical service later in the cure schedule. We give you a clear return-to-service timeline before the install so you can plan production around it.
Sometimes, but usually we remove the failed system back to clean concrete first. Installing over a failing layer just inherits its failure mode. The honest scope often includes removal as a line item; the quote tells you up front.
Client reviews
What Oshawa Operators Say About Their Epoxy Floors
Three contractors quoted slab prep as a paint roller and a primer. Oshawa Concrete quoted diamond grinding and explained why. Two years in, floor is still tight to the slab, no peeling.

Warehouse Manager, Oshawa
★★★★★
Service-bay system rated for hot tires and automotive fluids. Wash-down works, no spalling at the floor drains, and the slip aggregate is doing its job in winter.
Q. U.
Service Garage Owner, Toronto
★★★★★
They specced the system to the actual chemical exposure in our plant, not the cheapest option that fits the budget. Worth every dollar; the previous floor had failed in 14 months.
X. U.
Manufacturing Plant Manager, Brampton
★★★★★
Coordinated install around our shift schedule. Floor was returned to service at the timelines they quoted, no surprises, no slipped delivery dates. Real professionals.
